A Markov chain yog stochastic qauv piav qhia txog ib theem zuj zus ntawm cov xwm txheej tshwm sim uas cov qhov tshwm sim ntawm txhua qhov xwm txheej tsuas yog nyob ntawm lub xeev tau txais hauv qhov xwm txheej dhau los.
Cia li saib qhov no, koj txhais li cas los ntawm Markov saw?
A Markov chain yog ib txoj kev ua lej uas muaj kev hloov pauv ntawm ib lub xeev mus rau lwm qhov raws li qee qhov kev cai yuav tshwm sim. Lub ntsiab yam ntxwv ntawm a Markov chain yog tsis muaj teeb meem li cas txheej txheem tuaj txog ntawm nws lub xeev tam sim no, lub xeev yav tom ntej tau raug kho.
Ib tug kuj yuav nug, qhov txawv ntawm Markov saw thiab Markov txheej txheem yog dab tsi? Cov Qhov sib txawv ntawm Markov chains thiab Markov txheej txheem yog hauv index set, chains muaj lub sijhawm tsis sib xws, txheej txheem muaj (feem ntau) tas mus li. Random variables zoo li Guinea npua, tsis yog npua, los yog los ntawm Guinea. Random variables yog functions (uas yog txiav txim los ntawm txhais).
Tom qab, lo lus nug yog, Markov saw siv rau dab tsi?
Markov chains yog siv rau xam qhov tshwm sim ntawm cov xwm txheej tshwm sim los ntawm kev saib lawv li. lub xeev hloov mus rau lwm lub xeev, lossis hloov mus rau tib lub xeev raws li yav dhau los. Peb ua tau. coj huab cua ua piv txwv: Yog tias peb arbitrarily xaiv qhov yuav tshwm sim, kev kwv yees hais txog qhov.
Dab tsi yog homogeneous Markov saw?
markov - txheej txheem graphical-model graph-theory. Kuv kawm tias a Markov chain yog ib daim duab piav qhia txog yuav ua li cas lub xeev hloov lub sijhawm, thiab a homogeneous Markov saw yog xws li ib daim duab uas nws qhov system dynamic tsis hloov.

Dab tsi yog qhov kev tshwm sim handler hauv Visual Basic?
Tus neeg saib xyuas qhov xwm txheej yog tus lej koj sau los teb rau qhov xwm txheej. Tus neeg saib xyuas qhov xwm txheej hauv Visual Basic yog tus txheej txheem Sub. Hloov chaw, koj txheeb xyuas cov txheej txheem ua tus tuav haujlwm rau qhov xwm txheej. Koj tuaj yeem ua qhov no nrog rau Handles clause thiab WithEvents sib txawv, lossis nrog AddHandler Nqe Lus
Yuav ua li cas tshwm sim thaum cuam tshuam tshwm sim hauv microprocessor?
Kev cuam tshuam yog ib qho mob uas ua rau microprocessor ua haujlwm ib ntus ntawm lwm txoj haujlwm, thiab tom qab ntawd rov qab mus rau nws txoj haujlwm dhau los. Kev cuam tshuam tuaj yeem yog sab hauv lossis sab nraud. Daim ntawv ceeb toom tias thaum qhov cuam tshuam (Int) tshwm sim, qhov kev zov me nyuam nres ua haujlwm thiab microcontroller pib ua rau ISR
Dab tsi yog qhov tshwm sim tau tsav hauv NodeJS?
Los ntawm kev txhais, NodeJS yog qhov kev tshwm sim-tsav uas tsis muaj kev txwv tsis pub khiav sijhawm ib puag ncig rau JavaScript uas tau dhau los ua neeg nyiam heev ntawm sab server. Qhov no yog vim Nodejs muaj qhov xwm txheej-tsav architecture muaj peev xwm ntawm asynchronous I / O
Dab tsi yog qhov kev tshwm sim tuav hauv Web technology?
Event Handling yog ib qho software niaj hnub uas ua haujlwm, xws li keystrokes thiab nas txav. Nws yog qhov tau txais ntawm ib qho kev tshwm sim ntawm qee qhov kev tshwm sim los ntawm tus tsim khoom thiab cov txheej txheem tom ntej
Dab tsi yog qhov tshwm sim tshwm sim?
Ib qho 'kev mob tshwm sim' yog txhua yam uas cuam tshuam rau qee yam sab nraud ntawm qhov kev ua haujlwm raug tua. Cov haujlwm uas ua haujlwm yam tsis muaj kev phiv yog hu ua 'ntshiab' ua haujlwm: lawv siv cov lus sib cav, thiab lawv rov qab muaj nuj nqis. Tsis muaj dab tsi ntxiv tshwm sim thaum ua haujlwm
